A genomic region of lactococcal temperate bacteriophage TP901-1 encoding major virion proteins
Two major structural proteins, MHP (major head protein) and MTP (major tail protein), from the lactococcal temperate phage TP901-1 were sequenced at their amino acid termini, and derived degenerate oligonucleotides were used to locate the corresponding genes in the phage genome. This genomic region was sequenced.
The sequence characterized includes a total of 11 open reading frames (ORFs), showing an operon structure. Upstream of each ORF, except ORF b2 and ORF x, potential ribosome-binding sites were found, suggesting independent translation. However. coupled translation is suggested for ORF x and as a possibility for ORF b3 and ORF c2, which have ribosome-binding sites located more distant from their start codons.
ORF b2 may be translationally fused with mhp at a low frequency. The mhp and mtp genes are transcribed as a 3.7-kb mRNA with at least six additional ORFs. The organization of the genomic region analyzed resembles that of other distantly related phages, providing possible roles for the uncharacterized ORFs.
